UMBRELLA DEVI CE Filed Sept. 30, 1927 Patented Nov. 12, 1929 UnirseSTATES AUGUST KORTENBACH, JR., F EYER, GERMANY UMBRELLA DEVICE fApplication filed September 30, 1927, Serial No. 223,158, and in GermanyFebruary 24, y1926.

In the known automatically opening umbrellas the releasing ot the endsof the umbrella ribs andof the umbrella slide 1s el'lected by a simplehand operation7 for instance by that such a spring pressure or pull hasto be exerted that the release of the device 'for holding the umbrellain the closed position is possible only by using a certain amount ofpower. Moreover the mounting el the umbrella cover causes difficultiessince this is possible only when the umbrella is in a middle positionbetween its normal open and closed position,

that is to say when the umbrella is in siich a,

position that the ends of the umbrella ribs are released by theretaining errule but the uinbrella is not completely open.

According to the present invention an antomatically opening umbrella isprovided in which the intermediate position above reerred to can beobtained as desired7 the arrangement being such that when the ferrule olthe umbrella is withdrawn7 iirst ol all only the ends of the umbrellaribs are released. This first part of the opening operation can beseparated 'from the second part of the iopening operation-that is to saythe complete opening of the umbrella by the release of the umbrellaslide-, any desired interval of time being left between the two parts ofthe opening operation. However the arrangement is such that the twoparts of the opening oper.- tion can follow immediately one after the 40other by the retaining ferrule of the umbrella ribs being withdrawn to agreater extent.

ln order to prevent the complete opening of the umbrella owing tocarelessness or inadvertence? the release of the umbrella `slide isetfected after a greaterl resistance is overcome than the resistancethat has been required for releasing the ends of the umbrella ribs.

The invention is illustrated by way of eX- ample in the accompanyingdrawings in which@ by means of a bolt or pin z' which traverses the 'i fFigure lis a longitudinal section showing l), the umbrella slide l beingin that case locked by the catch e. The ferrule b is pro- G5 vided inits interior and approximately in the middle with a ring which isusedfor yguiding a sleeve f which 1s bent yover at the end near the saidring so as to form a flange and which is surrounded by a helical spring'T' g. Theone end of the latter spring abuts against the ring b whilstits other end abuts against a sleeve it which is placed on the sleeve f.The two sleeves are connected together Cil said sleeves and is rivetedthereto. A kconnecting link c is secured at one end to the said pinwhilst the catch e above referred to is pivotally secured to its otherend. The pin i rests against a helical spring Z which is are0 rangedwithin theumbrella stiel; @and said pin is guided in slots p, p formedin a third sleeve m, a having portions of different diameters and bein(rarranged in the handle g of the umbrella. As the second spring is mount-S5 ed in the interior of the umbrella stick it is possible to providethe device on handles of any kind.

Vhen the lerrule I) is withdrawn against the action of the spring g theends a of the umbrella ribs are freed from the errule. If the ferrule isnow released, the umbrella is in a half opened position in whichposition ther cover of the umbrella can easily be mounted. The completeopening oi the umbrella is et- 9FL fected only by the ferrule beingwithdrawn to such an extent that the bolt ory pin z' coinpresses thespring' Z until the catch e becomes disengaged from the umbrella slided.

What I claim is l. Device for releasably holding an umbrella closed,including a movable errule for retaining the ends of the ribs, a slidemounted on an umbrella stick, a catch capable ot engaging with andbecoming disengaged from said slide, a sleeve relatively to which theferrule can be displaced, another sleeve surrounding said sleeve andhaving an abutment, a spring capable of beingy compressed against thesaid abutment when thevterrule yis Withdrawn to a predetermined extentto release the ends of the umbrella ribs and asecond spring7 said stickhaving a handle 1within which said second spring 1s located,

ka transverse pin connected to said sleeves and pressing on top of thesecond spring and a link secured to the transverse pin and pivotallyconnected to the catch whereby When the lerrule is further Withdrawn thesecond spring is compressed by thetransverse pin until the catchl isreleased Jfrom the slide as and for the purpose set forth.

2. A device for releasably holding an rumbrella closed including amovable 'errule for retaining the ends of the umbrella ribs7 a slidemounted on an umbrella stick, a catch capable of engaging With-andbecoming disengaged rom said slide, a spring capable of being compressedWhen the ferrule is Withdrawn to a predetermined extent to release theends ot the ribs, a second spring capable of being compressed under theaction of the first spring when the Jerrule is further Withdrawn, and alink actuated by said ferrule against the action Aof said second springto release the catch from the slide.

vlntestimony whereof l have signed my name to this specification.
